OPERATING-TABLE FOR USE IN ANIMAL RESEARCH.

Specification of Letters Patent.

Patented Mar. 3, 1914.

Application filed May 10, 1913. Serial No. 766,769.

To all whom it may concern:

Be it known that I, KATHARINE STsanINs, a citizen of the United States, and a resident of the city of New York borou h of Manhattan, in the county and tate of New York, have invented a new and Improved Operating-Table for Use in Animal Research, of which the following is a full, clear, and exact description.

My invention has for its object to provide an o crating table for use in animal rcsearci, which will meet every demand of convenience and asepsis.

The operating ta is is constructed Wltll posts having hooks at their upper terminuls, which engage eyes of adjustable leaves which rest on cross bars supported on screws which mesh in threaded openings in the table, so that by turning the screws the cross bars may be raised or lowered carrying with them the leaves. The sides of the leaves are curved over the lugs, which permits the movement of the leaves without interference by the hooks on the posts.

Additional ob'ects of the invention will appear in the ollowing complete specification, in which the preferred form of the invention is disclosed.

In the drawings similar characters of ref-v erence indicate corresponding parts in all the views, in which- Figure 1 is a pers ective view showing how the operating tab e is used; Fig. 2 is an enlarged transverse sectional view of the operating table; Fig. 3 is 0. Ion itudinal sectional view of the o crating ta le; and Fig. 4 is a view of one o the leaves.

The faults found in the operating racks for animals hitherto used have been many. These 0 crating racks hitherto used have been in exible, making it difiicult to adjust them for animals of various sizes, and the racks have been manufactured of wood, and if unpainted, the absorbability of the wood has made them objectionable, while, if they have been covered with paint, the paint sticks to the animals fur, when wet with chemicals or blood.

Other im ortant improvements in my operating tab e are the convenient manner of draina e, and most important of all, the possibi ity of carr ing on the experiments under conditions 0 pro er asepsis.

In the use of dogs 0 the available'type, where the skin and hair are particularly difiicult to clean, the latter objection becomes a serious one, with the operating racks hitherto used, but this does not present any difliculty with my improved operating table.

As will be seen by referring to the draw ings, a table or support 5 is rovided, to which are secured the upward y extending posts 6, having outwardly disposed hooks 7 at their upper terminals. These posts 6 are spaced apart, at each side of the table or support 5, and the hooks 7 are ada ted to engage the eyes 8 in the de ending ugs 9, secured to the leaves 10 in t e channels 11. These leaves 10 are two in number, disposed horizontally, and diverging u wardly, and with their upper and outer si es supported by the enga ement of the hooks 7 with the eyes 8, in the manner which has been described. The channels 11 afiord ample room for the hooks 7, when the leaves 10 are moved outwardly. The lower and inner sides 12 of the leaves 10 are supported on the two cross bars 13, which are disposed adjacent the ends of the leaves. These cross bars 13 are held above the table or support 5 by the screws 14, which are disposed in seats 13" in the under sides of the cross bars 13, and which mesh in the threaded openin s 15 in the table or support 5. It will there ore be seen that by turning the hand wheels 16 on the screws 14, the screws may be turned to raise or lower the cross bars 13 as may be desired.

Disposed on the table or support 5, and between the screws 14, there is a pan 17, for collecting the drainage which passes to the an between the inner and lower sides 12 o the leaves 10. There are also slots 18 in the leaves 10, as additional means for drainage. The pen 17 has an opening 19, which re isters with an opening 20 in the table, be ow which is disposed a ail 21, supported on a book 22, secured to t e table or support 5, for receiving the drainage from the pan 17.

At the sides of the table or support 5, there are cleats 23, to which may be tied the cords 24, which may be tied to the legs 26 of thesanimal, and pass through the open- 111 2 aving thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a device of the class described, a support having a threaded opening, a lurality of posts secured to the support an having hooks, two leaves having in s with eyes in which the hooks are norma ly disposed, a member engaging the under side of the leaves, and a screw meshing in the opening for supporting the member.

2. In a device of the class described, two horizontally disposed leaves, having their sides disposed upwardly and outwardly, pivotal means engaging the leaves and disposed at a distance from the inner edges of the leaves, and a member engagil the inner edges of the leaves and i1(l]l1SlZtib e vertically relatively to the pivotal means for supporting the caves in adjusted position.

3. In a device of the character described, a table, a lurality of posts at opposite sides of the tab e and having hooks extending outwardly, two leaves, lugs secured to the under sides of the leaves adjacent the outer ed es of the leaves, the leaves extending inwar ly from the in s greater distances than the distances of tie hooks from the table, there being eyes in the lugs, in which the hooks are normally disposed, and means for supporting the inner edges of the leaves.

4. In a device of the class described, a support, a plurality of posts extending upward from the support, hooks on the posts, leaves having openings in their sides, means on the leaves with which the hooks ivot-' ally engage, cleats on the supports f r securing cords passing through the openings,

and transverse means for supporting th leaves in raised position and relatively to the posts.

5. In a device of the class described, a support, a plurality of posts extending upward from the support, hooks on the posts, leaves having openings in their sides, means on the leaves with which the hooks pivotally engage, cleats on the supports for securing cords passing through the openin s, and a cross member disposed under t e leaves, and means engagin the support for holding the cross member t ereabove.

6. In a device of the class described, a support, a plurality of posts extending upward from the support, books on the posts, leaves having 0 enin 's in their sides, means on the leaves with which the hooks pivotally engage, cleats on the supports for securing cords assing through t e openings, means for holding the leaves in raised position and relatively to the posts, and a tray disposed on the supports and disposed under the leaves.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
